Abstract: An intercarrier sound system is provided in which a single transistor is used as both the intercarrier sound mixer and a sound I.F. amplifier. The transistor has an input circuit which includes its base-to-emitter junction, and an output circuit including its collector electrode and one of its base and emitter electrodes. Picture and sound carrier signals are applied to the transistor by way of the input circuit and are mixed across the base-to-emitter junction of the transistor. Means are provided at an electrode of the transistor common to the input and output circuits having an impedance which varies inversely with frequency. The variable impedance means causes the amplification provided by the transistor to vary directly with frequency over a band of frequencies including the video signal and the intercarrier sound signal frequencies.

Abstract: In order to reduce the tendency towards cracks in the bottom of the teeth of saws by increasing the capacity of the saw to withstand dynamic loading, the inherent stresses in the saw blade are redistributed by plastic deformation in the region of the root of the bottoms of the saw teeth. According to a preferred form of embodiment, the deformation takes place from the sides of the saw blade, the tools being applied so that they are directed substantially straight against the roots of the teeth. In this manner an improvement of about 50% in the fatigue strength under dynamic loading can be achieved. The method is intended in particular for application to saws which are not intended to be resharpened, such as circular saws, band saws and frame saws which are equipped with hard metal or covered with stellite.

Abstract: A sound synthesizer in which pulses of a period indicated by a fundamental period parameter are produced by a fundamental period sound source, the output from the fundamental period sound source or the output from a noise source is selected depending on whether a sound to be synthesized is a voiced or unvoiced sound, and the selected pulses are applied to a sound synthesis filter section 16 to synthesize the sound. The sound synthesis filter section is composed of a second- order filter means (57-61, 65-69) which serves as a second- order filter having the zero on a unit circle in a complex plane, means for cascade-operating second-order filter means of different coefficients, and feedback means 41, 42 for feeding back the output from the synthesis filter section 16 to the input side through two kinds of such cascade-operating means, and coefficients of the second-order filters are controlled by control parameters. <IMAGE>

Abstract: A control system is provided for a programmable manipulator having an arm movable in a plurality of axes that results in improved dynamic performance and control of a manipulator arm over a wide range of arm loads, dynamic operating parameters of the arm, and over the full range of arm operating positions. The control system for one or more of the controlled axes includes several servo control loops utilizing force or pressure feedback from the axis actuators and variable inertia scaling of selected loop command signals and loop parameters. The variable inertia scaling in accordance with the inertia of the arm provides improved dynamic performance of the manipulator arm while maintaining stable servo-loop operation over a wide range of operating parameters. In a preferred arrangement, the variable inertia scaling is accomplished by the use of a look up table with appropriate interpolation of the table entries. The look up table is stored in a digital axis processor with the appropriate variable inertia scaling factors being determined by the axis processor for use by the respective axis servo-loop. The look up table in accordance with various predetermined operating requirements of the manipulator apparatus includes data entries representing inertia scaling factors according to the mass of the arm load, the commanded velocity in a particular axis, and the operating positions of one or more of the major control axes of the arm.

Abstract: Various processes relating to the in-situ retorting of oil shale are claimed. One process comprises rubblising a discrete bed of raw oil shale and then heating the bed to pyrolyse the kerogen in the shale, heating being effected by supplying a hot retorting gas in such a way that the pressure in the bed cycles between high and low values. Another process comprises injecting ait into a spent (previously retorted shale bed to cause combustion of char, thereby heating the bed and generating flue gas; discharging the flue gas; injecting a retorting gas; and transferring the thus heated retorting gas to a raw shale bed to supply heat for retorting.

Abstract: A lignin-containing feed material in particulate form is mixed with a process-derived slurrying oil and fed into an ebullated catalyst bed hydrocracking reactor. Reaction conditions are maintained at 650 DEG -850 DEG  F. temperature, 500-2500 psig hydrogen partial pressure and space velocity of 1.0-10 wt. lignin/hr./wt. catalyst. The reaction products are phase separated to recover hydrogen and slurrying oil, and the resulting liquid stream is passed to a thermal hydrodealkylation step. The reacted stream is fractionated to produce phenol and benzene products, along with a heavy alkylated material which is recycled to the hydrodealkylation step to increase the yield of phenol and benzene.

Abstract: A hand link for a robot with a bending motion about a first axis of rotation X and a rotational movement about a second axis Z, which is perpendicular to the first axis X. The bending and rotational motion is produced by drive motors via one or more herringbone gear transmissions. Adjustment of gear play is achieved by shifting a gear 22 or 30 along the deflection axis X against a pinion 45 or 52. A gear 30 in the transmission for the bending motion is joined to a unit 8 which contains the rotating axis 11 of the hand link with tool holder 19 and a gear 22 in a transmission for production of the bending motion via a coupling 35, which allows axial shifting but provides a fixed axial and tangential interconnection. Adjustment of the gear play in each of the transmissions making up the hand link can be done without affecting the play in the other transmissions. <IMAGE>

Abstract: A centrifugal pump having an impeller rotatable about an axis of rotation at its center has its operation controlled so as to regulate the size of a gas bubble. When pumping a liquid or suspension (such as paper pulp with a consistency of about 8-15 percent) which contains gas, the gas has a tendency to collect adjacent the impeller center, and impede operation of the pump. Using a number of electrodes which extend into operative association with the chamber of the pump in which the gas bubble tends to collect, and by taking advantage of the differences in electrical conductivity of the gas as compared to the liquid or suspension being pumped, the size of the gas bubble may be determined. When the size is too large, gas is automatically discharged from the pump. When an asynchronous motor drives the impeller, the pump power consumption can also be determined, and additionally the gas bubble size may be used to regulate the pump pressure head and the speed of the pump in order to obtain optimum operating efficiency.
